• the door closers can also enable functions such as keeping open or automatic closing. Usually the majority of these door closers are only suitable for opening the swing door in one direction. For swing doors, special measures are required to enable the functions of the door closer in both directions.
• a particular disadvantage is that, especially with doors made of glass, the door closer is either visible, or must be arranged very expensive in the ground, as this, the floor must be picked up to make room for the bottom door closer.

• a counterforce must be applied, so that the stop perma- nent is pressed against the cam.
• An inexpensive way is to equip the damper cartridge with a compression spring that presses the stop against the cam. This ensures that the stop and cam are permanently in contact.
• the open and closed holding function is generated by a arranged on the axis of rotation locking device.
• the locking device With the locking device, the possibility is created to hold the door in predetermined positions, so that z. B. by wind loads, the door does not swing back and forth. It is also possible with the locking device, the door z. B. at an opening angle of 90 ° open without a possible closing function, the door always moves to the zero or closed position.
